Iyochinja chepiezoelectricine VPM (Versatile Piezoelectric Module) yakamanikidzwa mukamuri resimbi rakasimba. Piezoelectric element module zvinhu zvinogadzira voltage mukupindura kushushikana kwemuchina. Ichishanda zvichienderana ne "piezoelectric effect," kumanikidzwa kwemuchina (semuenzaniso, kumanikidzwa kubva pamunwe) kunogadzira voltage inovhura kana kuvhara circuit.
Saka, kana ikadzvanywa, chinhu che piezoelectric crystal chinoburitsa shanduko inoenderana mu voltage inotumirwa ku circuit board kuburikidza nezvinhu zvinobatanidza zvinofambisa mhepo, zvichitevedzera dry contact switch closure, zvichivimba ne piezoelectric effect kuti ibudise pulse pfupi "on" iyo nguva yayo inogona kusiyana zvichienderana nehuwandu hwekumanikidzwa kuri kushandiswa.
Kana ikamanikidzwa nekumanikidzwa kwakanyanya, magetsi akakwira uye akareba anogadzirwawo. Nekushandisa mamwe macircuitry nemaslider, pulse iyi inogona kuwedzerwa kana kuchinjwa kubva pa "on" state pulse kuenda pa "off" state pulse.
Panguva imwe chete, i capacitor ine basa rekuchengetedza chaji, zvichiita kuti ikwanise kuwedzera hupenyu hwebhatiri. Tembiricha yekushanda inogona kunge iri pakati pe -40ºC ne +75ºC. Chinhu chikuru ndechekushaikwa kwezvikamu zvinofamba, zvakaita semasprings kana ma lever, izvo zvinoita kuti isiyane nemamwe ma switch echinyakare emakanika.
Kugadzirwa kweswitch imwe chete kunoita kuti ivharwe nehunyoro neguruva (IP68 na IP69K), zvichiita kuti isakuvadzwe kana kukuvadzwa nezvinhu zvekunze. Dzinoonekwa kuti dzinokwanisa kushanda kusvika mamiriyoni makumi mashanu, hadzipindi mvura, hadzipindi mvura uye dzinogara kwenguva refu kupfuura switch dzemakanika.
Nekuda kwezvinhu izvi, hapana mukana wekusakara, izvo zvinowedzera hupenyu hwazvo hwekushanda. Uye vakawana mashandisirwo mumaindasitiri akasiyana-siyana. Anogona kushandiswa mukufambisa, kudzivirira, kugadzira chikafu nemaresitorendi, zvikepe zvemugungwa nezveumbozha, mafuta negesi, uye indasitiri yemakemikari.
